Inhalt:
In NPC2 topology a very high current and a transient current peak (Itp) can occur in a special NPC2 short circuit mode (SCNPC2). A detailed description of that effect can help to protect IGBT power modules in this topology against malfunction and can help during a post mortem analysis to understand the root cause. With a full understanding of that effect the lifetime of the inverter can be increased and the time and costs for qualification reduced. In this paper we discuss how typical application parameters like temperature and gate driver can influence that effect.
